Mendeleev's periodic system arranged elements based on increasing Atomic Mass and grouped them by similar chemical properties, revealing periodic trends. He predicted the existence and properties of undiscovered elements by leaving gaps in his table, demonstrating the periodic nature of elements. Additionally, Mendeleev's system highlighted the relationship between atomic structure and elemental behavior, laying the groundwork for the modern Periodic Table.
What else can I help you with?
What value was there in predicting the properties for gaps in Mendeleevs table?
DiscoVery of new elements
What were mendeleevs discoveries and predictions and discoveries abot the periodic table?
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.
What was the problem with Mendeleevs table?
He left too many spaces between the elements......
What are the properties that include system file properties?
System file properties can include attributes such as read-only, hidden, system, and archive. These properties determine how the file behaves within the operating system and how it can be accessed or modified by users or applications. Understanding and managing these properties are essential for maintaining the integrity and security of system files.
Does Automatically updated properties include file system properties?
Automatically updated properties in a system typically refer to properties that are updated automatically by the system itself based on certain criteria or events. File system properties are usually not included in this category as they are usually managed and updated by user actions, operating system commands, or application interactions rather than automated processes within the system.
Which kind of properties fell into families or groups in Mendeleevs system of elements?
Non-metals and Metalloids

Did Mendeleevs group his elements with those of similar properties?
Yes, this affirmation is true.
Mendeleevs periodic table was useful because it enabled scientists to predict properties of unknown?
elements
Which matches Mendeleevs prediction for the properties of eka-aluminum?
It would be a soft metal with a low melting point.
Main idea of mendeleevs first periodic table?
In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses and repeating periodic properties.
What were mendeleevs discoveries and predictions and discoveries abot the periodic table?
Mendeleev predicted that properties of elements are periodic function of atomic mass. He demonstrated it by creating a table.
What effect did the discovery of the gallium have on the acceptance of Mendeleev's table?
The close match between Mendeleevs prediction and the actual properties of new elements showed how usefullhis pariodic tabel could be.
What effects did the discovery of gallium have on the acceptance of Mendeleev's tables?
The close match between Mendeleevs prediction and the actual properties of new elements showed how usefullhis pariodic tabel could be.
What was the problem with mendeleevs arrangement?
He pooped quite a bit
What makes up the halogen triad?
This refers to an old "history of science " topic around the work done prior to mendeleevs on Periodic Table. Elements were put in triads with similar properties. The halogen triad was chlorine, bromine and iodine. Pretty useless idea long term but a good start for people who came later.
How could Mendeleevs table be used to predict the properties of elements that had not been discovered?
Mendeleev's periodic table allowed for the prediction of the properties of unknown elements by identifying gaps in the table where elements had not yet been discovered. By examining the properties of neighboring elements, Mendeleev was able to predict the properties of the missing elements and suggest their existence. His periodic table provided a framework for organizing elements based on their atomic mass and chemical properties, which allowed for the accurate prediction of the properties of undiscovered elements.
